Hand Scan Tester Demo Electronics. We don't see how this performs any useful function other than to demonstrate some sort of sensor. When first turned on, it comes up in an alarm state with the buzzer on and the red LED indicator lighted. When your hand is over the sensor (where the tiny green LED is) the amber light comes on. When your hand is gone, the green light comes on. (objects other than a hand work too). There is an included hand switch, the function of which is not clear to us. There are 3 smaller LEDs on the back with the buzzer that mimic what the larger industrial indicators do. Similar items may be available listed separately or on request. Might be just what you need for your optical sensor demonstration application. Condition looks good used as shown except that we don't have a lens for the red industrial indicator.
